Tracing new physics through the structure of the Universe.
I study how axions, primordial fluctuations, and nonstandard dark matter leave observable signatures across large- and small-scale cosmic structure.
Research program
Fundamental models. Observable consequences.
My work moves between formal theory, numerical simulation, cosmological inference, and AI-assisted scientific reasoning.
Early Universe
Axions & primordial fluctuations
Blue isocurvature spectra, rotating complex fields, nonlinear dynamics, and non-Gaussian signatures.
Cosmic Structure
Warm, fuzzy & mixed dark matter
Connecting nonstandard dark-matter models to structure formation across cosmic scales.
Inference
LSS, EFTofLSS & UV luminosity functions
Using galaxy clustering and high-redshift galaxies to test early-universe and dark-matter physics.
AI in Physics
TPBench & scientific reasoning
Evaluating advanced AI models on theoretical-physics problems, from undergraduate concepts to research-level reasoning.
